Frequently Asked Questions

What is the GOST Ex certification for?

The GOST Ex mark means this V18345-1027420001 is approved for use in explosive atmospheres according to Russian and Eurasian technical regulations.

What does 'fail-safe' mean for a double-acting unit?

In a power failure, the positioner vents air from both actuator chambers, causing the valve to move to its predefined safe position (open or closed).

Can I add position feedback later?

Yes. The design allows for later installation of plug-in analog or digital feedback modules as optional upgrades.

What is the LKS adapter plug for?

The LKS adapter facilitates easy connection and disconnection of the input signal wires during maintenance or installation.

How is the travel time prolongation used?

This function slows down the actuator's movement, useful for preventing water hammer or protecting delicate equipment from rapid valve shifts.
